A little something from my darker days:

They all walk on the pier, invisible to one another. Heads sunk, they catch glimpses of the raging water below and wish to dare to feel as powerful as the tide. Tingles surge through them when the invisible try to bring them back, yet they only stop momentarily confused and continue, body returning to numb. Their secret desire is to slip through the boards of the pier, for in the water they can be rescued; they once heard of lifeguards before they began this dismal journey. Right foot, then left. They walk along the pier, the never ending planks, invisible to one another. They are not selfish, they are trapped.
